DN05052/D, 120 VAC, Low-Cost, Dimmable, Linear Parallel-to-Series with Switch-In CCR LED Lighting Design Circuit

DN05052/D, Design Circuit is an innovative take on the parallel-to series topology and provides an effective 120 VAC LED lighting solution. Its primary features are its PF and THD performance, dimmability, low cost, and high efficiency and light output. This circuit uses a parallel-to-series topology that dynamically adjusts LED forward voltage as the bridge output varies. The circuit also switches two CCRs independently to match the input current waveform to the bridge output voltage for excellent PF and THD performance. The circuit is designed for input voltages between 110 VAC and 130 VAC
